Menangani A PHP Error was encountered Severity: Warning Pasca Install Pustakawan Pathfinder

Kemarin saya telah share cara install Pustakawan Pathfinder. Setelah install Pustakawan Pathfinder , ternyata eror terdapat pesan seperti berikut ini

A PHP Error was encountered

Severity: Warning
Message: mkdir() [function.mkdir]: No error
Filename: drivers/Session_files_driver.php
Line Number: 117
Backtrace:

Function: __construct

File: D:\psenayan\apache\htdocs\pustakawan\index.php

Function: require_once

An uncaught Exception was encountered

Type: Exception
Message: Session: Configured save path '' is not a directory, doesn't exist or cannot be created.
Filename: D:\psenayan\apache\htdocs\pustakawan\system\libraries\Session\drivers\Session_files_driver.php
Line Number: 119
Backtrace:

Function: require_once

 Setelah saya browsing saya menemukan artikel yang sangat membantu menyelesaikan masalah ini. Masalah error ini disebabkan masalah sesion driver.
Untuk menanggani nya :
1) Silahkan edit file config.php yang ada di folder pustakawan\application\config
2) Ubahlah code pada $config['sess_save_path'] dari NULL menjadi
sys_get_temp_dir();

Perhatikan code berikut

Code yang belum diedit

$config['sess_save_path'] = NULL;

Code yang sudah diedit
$config['sess_save_path'] = sys_get_temp_dir();

3. Refresh apache dan Pustakawan Pathfinder aman digunakan. Ayo gunakan Pustakawan Pathfinder
